“I will speak today until the president responds and says, ‘No, we won’t kill Americans in cafes. No, we won’t kill you at home at night,’” Mr. Paul said early on in the filibuster, which began at 11:47 a.m. and by early afternoon showed no signs of slowing down.

If Rand Paul thinks the government is so awful that it is planning to assassinate people then why is he asking that government for reassurances that it won't?

I don't see how he could accept anything that the administration says on this topic as some reason to stop his filibuster because he should not be able to trust them if they are as awful as he seems to believe that they are.
